摘　　要：桑蚕种良卵率是蚕种质量检验的重要指标,控制样本间卵粒数的偏差是保证良卵率准确性的关键。通过对桑蚕卵粒重的调查分析,得出其分布服从正态分布。若从一批蚕种中抽取1g卵作为样本,则来自同一总体的2个样本的卵粒数之差不超过16粒,其置信概率为95%;当置信概率取99%时,两个样本的卵粒数之差不超过21粒。文章为蚕业生产提供了一种实用的克卵粒数偏差控制方法。The percentage of good eggs is a very important quality index of silkworm eggs. Deviation control to samples of number of eggs is the key method to guarantee the accuracy of percentage of good eggs. The distribution of weight of eggs reconciled the normal distribution by to investigate and to analyze the weight of silkworm eggs. If extracted one gram eggs from a pile of silkworm eggs as a sample, then the difference of egg numbers of two samples is not over 16 eggs that the two samples come from the same general population, and its confidence probability is 95% ; when the confidence probability is 99%, the difference of egg numbers of two samples is not over 21. It provided a practical of the deviation control method to the number of eggs per gram for sericuhure in this paper.
